android: The google maps 8.4.0 version is crashing for some devices

We're facing an issue with the maps is some phones. Here's the open issue in the google repo. None of the comments on the issue is helpful.
We are using 8.4.0 version and we have no clue how to fix or catch this crash.
This is hapening only in some devices example : LGE LG-P970 Android 4.0.4 API 15.
We're using the SupportMapFragment.
The stack trace is not giving any details:

I observe this crash in activity which dynamically changes fragments when Android device connected to computer in USB debug mode. Without USB connection application works fine.

Android Facebook integration with proguard

I made sure the key hash I send to Facebook is the same as defined in the app settings on Facebook.
I added the following to the proguard-project.txt file:
-keep class com.facebook.** { *; }
-keepattributes Signature
and still I get the following error when my app starts:
com.facebook.as: com.facebook.c.f got an unexpected method signature: public abstract org.json.JSONObject com.facebook.c.c.c() at com.facebook.c.h.a(Unknown Source) at com.facebook.c.f.b(Unknown Source) at com.facebook.c.f.invoke(Unknown Source) at $Proxy0.c(Native Method) at com.facebook.b.bo.a(Unknown Source) at com.facebook.b.bo.onPostExecute(Unknown Source) at android.os.AsyncTask.finish(AsyncTask.java:632) at android.os.AsyncTask.access$600(AsyncTask.java:177) at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:645) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:5118) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:794) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:610) at dalvik.system.NativeStart.main(Native Method) java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:300) at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:355) at java.util.concurrent.FutureTask.setException(FutureTask.java:222) at java.util.concurrent.FutureTask.run(FutureTask.java:242) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:231) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1112) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587) at java.lang.Thread.run(Thread.java:841) Caused by: com.facebook.as: com.facebook.c.f got an unexpected method signature: public abstract org.json.JSONObject com.facebook.c.c.c() at com.facebook.c.h.a(Unknown Source) at com.facebook.c.f.b(Unknown Source) at com.facebook.c.f.invoke(Unknown Source) at $Proxy0.c(Native Method) at com.facebook.b.bn.a(Unknown Source) at com.facebook.widget.c.a(Unknown Source) at com.facebook.widget.c.doInBackground(Unknown Source) at android.os.AsyncTask$2.call(AsyncTask.java:288) at java.util.concurrent.FutureTask.run(FutureTask.java:237) ... 4 more
What am I doing wrong?

Reading on the internet made me realize that it relates to proguard so I added the following to proguard-project.txt as instructed:
-keep class com.facebook.** { *; }
-keepattributes Signature
but the same happens... what am I missing?
